What is the story of the tattoo that Simeone’s son kissed against Liverpool

Giovanni Simeone, the son of Atletico Madrid coach Diego Simeone, has kissed a tattoo he got at the age of 13, after scoring his first goal in the Champions League.
This came in Napoli’s 4-1 thrashing of Liverpool, and the 27-year-old could not believe his remarkable luck, when he was left unchecked in the penalty area, and stayed behind Virgil van Dijk, to score his team’s third goal before the end of the first half.
The goal in the 44th minute may have seemed easy, but for Simeone it was a dream come true, as evidenced by his amazing celebration.
In an interview with the Guardian last year, the Argentine announced his love for the first competition in Europe, which he embodied with a tattoo he got during his teenage years. I tattooed the logo.”
Giovanni Simeone added, “My father did not want me to do this, and my mother asked why, so I answered them, because I will kiss this tattoo on the day I play and achieve my first goal in Europe .. Europe .. Europe”, and he fulfilled his dream after 14 years.
